WAIT - rereading this... It's for PRE school? That changes everything. They're private companies. For-profit. They COST money to attend. They're essentially DAYCARE centers. Totally different from public schools.
anyone who has had a kid in pre-school will know....
it's WAY easier to just have the dude scoop out chicken nuggets, corn and applasauce for 20 three-year-olds, than open up lunchables, watch for choking, stop the kids from fighting, etc etc. Kids are a pain in the ass with lunches, and yeah, at 3-4 years old, they'll steal from each other.
and since pre-schools (at least in florida) are private businesses, not run by the state, well, I guess we can STFU about Obama hating on our rights and all that. If you don't like it, take your $ to another pre-school.
